Steel structure engineering quantity is so big, how to check and accept ability after completion rest assured?

Use steel structure as the raw material of engineering is certainly need acceptance after completion, how to avoid the leaking without acceptance of steel structure engineering, steel structure processing factory there is a voice, the steel structure of the building code to be executed in accordance with the standard, cannot careless, each stage need to check, it’s simply about eight criteria of acceptance:Strictly control the construction load of the roof, floor and platform, not more than the bearing capacity of beams, trusses, floor and roof board, after the formation of space units, the gap between the bottom plate of the column and the top of the foundation should be timely pouring of fine stone concrete, grouting, etc..The specifications of fasteners such as positioning shaft, foundation shaft, height and anchor bolt must meet the relevant design requirements. The allowable deviation of foundation support surface height is 3 mm, the allowable deviation of anchor bolt center is 5 mm, the allowable deviation of reserved hole center is 10 mm, and the allowable deviation of exposed length of anchor bolt is 0-30 mm.According to the acceptance code for steel structure engineering, the contact surface should be at least 70% of the inlet seam, and the distance between the side seams should not exceed 0.8mm.After the components into the site, timely check the vertical and horizontal bending vector height tolerance of the steel truss, compression members, check the vertical and horizontal displacement deviation of the steel column and the vertical of the column, for the multi-section column also need to be within the allowable deviation value.The vertical deviation of steel structure crane beam is within 1/5 of the total height of the crane, and the allowable deviation of transverse bending vector height is within 1/1500.The installation of the steel frame requires the use of wind ropes, winches and other tools to ensure its stability. After complete installation, a series of support systems such as column supports, tie rods, horizontal roof supports and, if possible, roof purlins should be installed to ensure the stability of the entire steel frame.Also need to check the roof support, diagonal support, diagonal support and support sleeve connection, to see whether the wall support, diagonal support, support connection is installed, but also check the steel column connection and the number.Check the connection position and number of horizontal support, rigid tie rod and pillar support in time.The whole steel structure engineering is not small, but for the acceptance of this is related to the later use, the whole acceptance process is carried out in accordance with the above 8 standards, are in line with the standards, so congratulations to you such steel structure engineering can be relieved to use.
